GABBETT, O1 HARTFORD, CONNECTICUT, ASSIGNOR TO THE ARROW-HART 8o H EGEMAN ELECTRIC COMPANY, HARTFORD, CONNECTICUT, A CORPORATION OF CONNECTICUT PLUBAL SWITCH OPERATING KEANS Application filed October 80, 1930. Serial No. 492,318.

In radio receiving sets all the amplifying tubes may be needed when the set is tuned to bring in a distant station but, it is often desirable to cut out a number of amplifying tubes when the set istuned to a local station. It is possible by means of known cir-' cuits to use a three element switch which when in oneposition will put all the tubes in circuit and'in the otherv position will cona single actuator to turn on the power switch and also to control the local-distance switch.

Another object of my invention is to provide a sin le actuator to control two toggle snap switc es which are adapted for use in the above circuit. Y

Another object of my invention is to provide an operating means for switches of the above type, which will be compact, easy to operate and composed of a small number of easily made parts. d

Other obgects willappear as my invention is describe inconnection with the accompanying drawing.

In the drawing A Ifi 1 is a side elevation view of a air of switc es and an operating means t erefor constructed according to the principles ofmy invention.

Fig. 2 is a plan'view of the switches and operating means'shown in Fig. 1.

Referring to the drawing, the switches A and B, which are to be controlled are toggle type switches havinga switch mechanism of t e t pe shown in Guett Patent N 0. 1,280,018, a

a nd aving a switch base and contact structure of the type shown in Guett Patent No. 1,744,629, dated January 21, 1930. In the present invention one of the switches, A, need only be provided with fixed contacts at one.

end of the base, since that switch will be used ordinarily only to make or break the circuit to the power supply. The other switch, B, however must have one or more ,contacts at each end of the base in order to control the circuits for local or distance reception as above mentioned. 1

Power switch A is controlled by a toggle lever 10 while local distance switch B is' controlled and actuated by an oscillatable sleeve 12 which is. connected with the switch mechanism. Both of these switches are secured u on a U-shaped metal bracket 14, the switch being secured by a nut screwed on a boss extending through a hole in one leg of the bracket while switch B is secured in a.

similar manner to the base of the bracket.

The toggle lever 10 and the sleeve 12 are both controlled and actuated by a reciprocatable and rotatable switch control shaft 16. This I control shaft is round and can slide and rotate within a bushing 18 located in the leg of the U-shaped bracket opposite to the switch B. The inner end of the control shaft 16 slidably engages the sleeve 12 and in order that this sliding relationship-may be maintained while at the same time the shaft 16 may rotate the sleeve 12, a key 20 is provided on the inner endeof the control member. This key slides in a longitudinal slot 22 in the sleeve. Thus when the shaft 16 is rotated the key 20 engagin one side or the other of the slot 22 causes the sleeve to be rotated to operate switch B.

In order to operate the switch A, the midportion of the shaft 16 is reduced in diameter,

as at 17, to fit within a slot in the spheroidal head of the to gle lever 10. The reduced portion '17 is just Tong enough to permit the reception of the spheroidal head of the toggle lever. Thus when the shaft 16 is pushed in or pulled out the shoulders adjacent the reduced portion of the shaft engage the spheroidal head to move the to gle lever and cause actuation of the switch A knob 30 is provided on the end of the control shaft 16 whereby the control shaft may be more easily reciprocated or rotated.

The full line position shown in Fig. 1 shows the power switch A on and the local-distance switch B in position to connect only a fewof the tubes for receiving local signals. The dotted line osition in F1%. 1 shows the power switch off and ocal-distance switch B in position to connect all the tubes for distance receiving. When the switch A is in either on or off position the switch B may be actuated to the dotted position by simply rotating the ,control member 1.6 counterclockwise. Thus either the local circuit or distance circuit can be completed by merely rotating the knob for a fraction of a revolution to cause the key 20 and slot 22 to occupy the full line position (local on), or the dotted line position (distance on).

AlthoughI have shown only two switches it is obvious that three or more could be actuated in the same manner. Therefore I do not vlimit my invention to the construction shown nor .to use in a radio receiving circuit, nordo I limit it to the specific construction of the switches shown herein or in Guett Patents Nos. 1,744,629 and 1,280018.

I claim:-

1. The combination comprising a bracket, a plurality of switches supported thereon, slotted operating members projecting from said switches, and a single control member having'means engaging in the slots of said operating members whereby predetermined movements of said control member will cause actuationof said switches.

2. The combination comprising a bracket,

slotted operating members projecting from said switchesgand a single control member having means engaging in the slots of said operating members, said control meinber being capable of rotation and reciprocation whereby at least one of said switches may be operated by reciprocation of said controlmember and at least one of said switches may be operated by rotation of said control member.

v 3. The combination comprising a bracket, a plurality of toggle switches mounted thereon, operating members projecting from said switches, a shaft engaging said members, 7

said'shaft being rotatable with respect to the first of said members and reciprocatable with respect to the second of said members, said first member being actuated upon reciprocation of said shaft and the second member being actuated upon rotation of'said shaft.

4. The combination comprising a bracket, a plurality of toggle switches mounted thereon, a lever projecting from oneof said switches, a sleeve projecting from the other of said switches, a shaft engaging with said sleeve and said lever whereby said lever may be moved upon reciprocation of said shaft, and said'sleeve may be rotated upon rotation of said shaft.

5. The combination comprising a bracket,

a bearing in said bracket, an operatingmember mounted in said bearing forrotation and reci rocation, a switch mounted in said brac ret and having a slotted lever projecting therefrom, another switch mounted in sai bracket and having a slotted sleeve projecting therefrom, said operating member telescoping with said sleeve and having a key engaging with said slot, said operating member also having a reduced portion fitting in the slot of said lever whereby said switches may be operated upon reciprocation and rofixation, respectively, of said operating mem- 6. The combination comprising a U -bracket, a bearing in one arm of said bracket, an operating shaft mounted in said bearing for rotation and reciprocation, a switch having a slotted lever projecting therefrom mounted in the base of said bracket, and another switch having a slotted sleeve projecting therefrom mounted in the other arm of said bracket, said operating shaft telescoping with said sleeve and having a key engaging in the slot thereof, said operating shaft having a reduced portion receiving said slotted lever, whereby said switches may be operated by reciprocation and rotation, respectively, of said operating member.

In testimony whereof I have signed my name to this specification.

JOHN D. GARRETT.
